Netherlands: Ministry of Economic Affairs and Climate Policy

The Ministry of Economic Affairs and Climate Policy tracks public procurement information in TenderNed.

TenderNed is the tendering system of the Dutch government. Dutch contracting authorities are required to publish their tender announcements on TenderNed. The obligation only applies to contracts above the European tendering thresholds and to the voluntary announcement of national contracts. The dataset contains all announcements: market consultations, pre-announcements, contract notices, corrections, contract award notices, early terminations and changes.

The dataset also contains additional fields that are not documented as extensions, such as: relatedNotices, awards/value/hasTax, awards/value/tax, parties/address/streetAddressDetails, tender/hasParticipationFees, tender/invitationDate, tender/isDigital, tender/nationalOrEuropean, tender/nature, tender/noticeType, tender/noticeTypeDetails, tender/registrationPeriod, tender/bidOpening/locality, tender/deliveryAddresses/id, tender/registrationPeriod/endDate, tender/value/hasTax, tender/value/tax.

Data quality


The dataset has minor issues that should not interfere with most uses. They include:

  • The field tender/procedure/features contains a large number of missing values
  • The fields tender/value and award/value contain extremely large values (e.g., 999999999999.99) which may be caused by data entry errors
  • An abnormally high share of tender and award values contain the specific values of 1 EUR or 0.01 EUR, possibly due to data entry errors or system configuration issues
